Hi Mark,
I wonder if it would not be possible to display NA or a * or -- when the instrument does not have a starting price in the time frame measured.
Please refer to the 5 and 10 year change in price in the report below. Although I have marked the 5 and 10 year columns some don't even have a 3 year history.
It would not always be possible to see it purely looking at the return value. Only because I know these instruments I can see the 5 and 10 year value is not correct.
Regards.
